After 7 months of testing behind closed doors Google has finally opening up Google Knol to the public. This site is similar to Wixipedia, but with more of an emphasis on the author of the post. You the expert can write your own Knol on the area of your choice. You then have the option to allow other people to edit your Knol or just suggest edits that you would need to approve. You can even make it so no one can ever edit your Knol. Google is basically building an encyclopedia for all of the worlds information from the ground up and is making it possible for its users to profit from it as well. That's right Google has made it so you can display Google Adsense on your Knol! So you to can make you money for your knowledge. The possibilities are endless...

Unlike the popular Second Life which cost $9.95 a month, like most things Google Lively will be completely free and only requires a plugin to get started. Lively's users will be able to sculpt an avatar that can be male, female or even a different species. An avatar can assume a new identity, change clothes or convey emotions with a few clicks of the mouse. You will also be able to create virtual rooms that you design yourself and visit your friends rooms, coffeehouses and even exotic islands! Google even gives you the ability to setup TV where you can watch Youtube videos in your room. A Google spokeswoman said that there isn't any currency in Lively, but that users will be able to add objects from Lively's catalog to their rooms free of charge. And users can't yet create their own items but should be able to down the road. This application already works on Facebook and Google is working to get it operational on MySpace. I can only imagine where it will go from here! Check out the video below for some screen shots...
